Abstract
A golf bag umbrella adapted for use in a golf bag for providing optimal protection to items stored within the golf bag, having an extendable and retractable shaft and a collapsible and expandable canopy, underneath which is a flexible material, preferably mesh or netting, for preventing the golf clubs from becoming entangled in the support structure for the umbrella canopy. The golf bag umbrella further includes a handle, providing easy movement between an extended position and a lowered position while the canopy is expanded, such that the golf clubs within the golf bag may be easily accessible without having to remove the golf bag umbrella from the bag. The protective material beneath the canopy functions to prevent entanglement between the golf clubs and the support structure of the canopy, which prevents damage to both the support structure and the golf clubs themselves while also avoiding frustration on the part of the golfer as the golfer attempts to remove golf clubs from within the golf bag.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to covers for golf bags and, more particularly, to an adjustable umbrella for use in a golf bag which provides optimal protection of golf clubs within the bag, while allowing for easy insertion and removal of the golf clubs.




Golf bags for carrying golf clubs, ball retrievers and other golf equipment and accessories are typically open at the top for easy insertion and removal of the golf clubs. While this provides easy access to the clubs, it also leaves both the clubs and the bag exposed to adverse weather conditions such as when rain is encountered while on the golf course. Exposure to such conditions makes it difficult to continuing playing around of golf as the handles of the clubs become wet and, over time, may even lead to damage of the clubs and the bag.




To address these conditions, various umbrella like covers have been developed to protect the upper end of a golf bag in situations when rain is encountered while on the golf course. However, many of these devices simply protect the golf clubs from the elements, but do not allow for easy removal and insertion of the clubs so that play may easily continue. Such devices may be adequate in cases when a golfer encounters a down pour and cannot continuing playing, but are very difficult to use in situations where there is a light rain or drizzle and the golfer wishes to complete the round of golf.




A typical umbrella device that allows for removal of clubs while the umbrella cover is expanded is disclosed in U.S. Pat. No. 5,297,570, to Conner. Conner provides an umbrella that is positioned above the golf bag and clubs and includes a spring joint such that the umbrella may be bent off to one side to remove the clubs from the bag. While such a design allows for insertion or removal of the clubs from the bag, it fails to provide optimal protection of the clubs during adverse weather conditions due to the fact that the umbrella cover is positioned substantially above the opening of the golf bag, thereby allowing rain to be blown into the space between the umbrella and the top of the golf bag, onto the golf clubs and into the golf bag with a minimal amount of wind.




Another approach to protect golf clubs from adverse weather conditions is to utilize an umbrella that may be lowered down over the golf bag top to better protect the clubs between golf shots and then extend upward to allow access to the clubs for the next shot. A substantial drawback to these proposed designs is that a typical umbrella cover is supported by a support structure made up of collapsible and expandable arms connected to the shaft of the umbrella, which arms extend radially outward to the umbrella cover itself. When such an umbrella is lowered over the golf clubs within a golf bag, the subsequent sudden motions of the golf bag and clubs, while being transported around a golf course, cause the heads of the clubs to constantly come into contact with the support structure, thereby becoming entangled within the support structure and even bending and damaging the support structure of the umbrella. Not only does this lead to a very short useful life of such an umbrella, as the support structure quickly becomes damaged beyond repair, but this also leads to frustration on the part of the golfer as it becomes an ongoing struggle to raise the umbrella, so as to remove a club, when several clubs are entangled within the support structure. In addition, in some situations, the support structure can even scratch, mar or otherwise damage the exposed club heads.




Still yet another approach to protecting golf clubs within a golf bag, while still allowing for insertion and removal of the clubs, is disclosed in U.S. Pat. No. 4,788,996, to Forshee. Forshee discloses a foldable golf bag cover that expands over the golf clubs in a golf bag and allows for removal of the clubs by pushing downward at its top, which causes the umbrella-like cover to invert and subsequently be pushed into a mounting tube projecting upwardly from the opening of the golf bag. Such a device again allows for insertion and removal of a club, but fails to provide protection to the other clubs while a selected club is removed from the bag or replaced into the bag, as the entire umbrella is collapsed each time a club is removed from the bag. An additional concern with this design is that it is very bulky, as the mounting tube has a very large diameter relative to the size of the clubs and thus takes up a substantial amount of space within the opening of the golf bag, even when it is not in use. This is a substantial drawback to an avid golfer, who typically has fourteen different golf clubs within the bag, so that there may not be enough room for a large diameter tube similar to the one disclosed in Forshee, especially if smaller, lighter carry bags are used. Furthermore, such a device is not easily stored in the golf bag during times when it is not raining. Even in its stored position, the large diameter tube extends upward from the opening of the golf bag to a point substantially above the heads of the longest clubs, and thus may interfere with a golfer's access to the golf clubs, regardless of whether it is raining or not.




Therefore, there is a need in the field of golf bag covers to provide a golf bag umbrella which offers optimal protection of the golf bag and the clubs therein while the bag and clubs are transported along the golf course, while also allowing for easy removal and insertion of a selected club for each shot during the round of golf. Furthermore, the golf bag umbrella must be durable as it is constantly in contact with the heads of the clubs, while also being easy for the golfer to raise and lower without the clubs being caught in its support structure. Finally, the golf bag umbrella must be collapsible and very compact such that the umbrella takes up a minimal amount of space within the golf bag when not in use.




SUMMARY OF THE INVENTION




In recognition of the above problems, the present invention provides a golf bag umbrella which results in optimal protection of golf clubs within the golf bag and yet provides easy access to the golf clubs while being easily inserted within the golf bag due to its compact size and collapsibility.




According to a first aspect of the invention, a golf bag umbrella for protecting items in a golf bag includes a shaft, a canopy and a protective cover. The canopy attaches to an upper end of the shaft and further includes an exterior surface, an underside and a support structure which supports the canopy and secures the canopy to the shaft. The protective cover extends over at least a portion of the shaft and support structure and is secured to at least one of the underside of the canopy and the support structure. The protective cover prevents items such as golf clubs within the golf bag from becoming entangled in and/or damaged by the support structure, while the support structure is protected from being damaged by the items within the golf bag.




According to another aspect of the invention, the golf bag umbrella may be easily extended upwardly from a lowered position over the golf bag, to provide for easy removal and insertion of golf clubs within the golf bag, while still providing adequate protection to the clubs remaining in the bag as the golfer removes a selected club for the next shot. After each shot is completed, the golf bag umbrella may be easily returned to its lowered position directly above the heads of the clubs, thereby providing optimal protection of the clubs and the bag.




Still yet another aspect of this invention is to provide a golf bag umbrella that is highly compact and easily stored within the golf bag, being collapsible to roughly the size of a typical golf club and taking up a minimal amount of space within the golf bag, when it is not in use.




These and other objects, advantages, purposes and features of this invention will become more apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now specifically to the drawings, there is shown in

FIG. 1

a golf bag umbrella


10


which is inserted within a cavity


12


of a golf bag


14


. Golf bag umbrella


10


includes a shaft


16


, a canopy


18


, a protective cover


20


, and, preferably, a handle


22


. Canopy


18


includes a cloth-like rain cover


23


, typically formed from flexible, water-resistant cloth or fabric, which is expandably and collapsibly secured to shaft


16


by a support structure


24


. Golf bag umbrella


10


is positionable in golf bag


14


such that canopy


18


may be expanded over an upper portion


26


of golf bag


14


, thereby protecting golf clubs or other items within golf bag


14


from adverse weather conditions. While expanded, canopy


18


of golf bag umbrella


10


may be positioned at a lowered position where canopy


18


is at a height slightly above the tallest golf club, such as a driver or the like, within golf bag


14


. Protective cover


20


then functions to prevent the golf clubs, shown generally at


30


, from becoming entangled within support structure


24


of canopy


18


.




As shown in

FIG. 2

, shaft


16


of golf bag umbrella


10


is preferably extendable to an extended position while canopy


18


remains expanded. This extended position allows the golfer to remove or insert golf clubs


30


within golf bag


14


from the space between the canopy and the top of the golf bag without interference from canopy


18


of golf bag umbrella


10


. Once the golfer has removed or replaced the selected golf club, the golf bag umbrella may be easily returned to the lowered position shown in

FIG. 1

, to again provide optimal protection from the weather of golf clubs


30


within golf bag


14


. Finally, as shown in

FIG. 3

, golf bag umbrella


10


is preferably fully collapsible, such that canopy


18


is folded and wrapped around shaft


16


, thereby providing a sleek, compact umbrella


10


for easy storage within golf bag


14


when it is not raining. Shaft


16


may also be fully retractable so that umbrella


10


may be collapsed to a size of a typical golf club and preferably to a size substantially similar to a short iron, such as a typical


9


iron or pitching wedge, thereby taking up a minimal amount of space within golf bag


14


.




Canopy


18


of golf bag umbrella


10


is preferably substantially similar to a standard, compact and collapsible personal umbrella, and includes both a support structure


24


and rain cover


23


. Rain cover


23


is preferably durable but also highly flexible and collapsible, and also substantially water repellant, and is typically made from a cloth-like woven fabric or membranous material, such as woven nylon fabric or the like. Alternately, flexible resinous plastic or composite materials such as thin vinyl sheeting or the like may be used. Support structure


24


of canopy


18


, as best shown in

FIG. 4

, may include a plurality of substantially straight and unattached or free arms


32


extending radially outward from an inner lower ring


34


to an outer pivot joint


36


, where free arms


32


hingably connect to a plurality of elongated, substantially straight but resilient attached arms


38


. Attached arms


38


are typically secured along an underside


40


of rain cover


23


, and further extend radially outward from outer joint


36


to a circumferential edge


42


of rain cover


23


where they are each secured to cover


23


, thereby providing rigidity to cover


23


towards its outer edge


42


when structure


24


is expanded. Support structure


24


may also include a plurality of downward extending arms


46


, which extend radially outward and downward from an upper ring


48


, upon which a center point


50


of rain cover


23


is secured (FIG.


1


). Downward extending arms


46


are hingably mounted near a mid-point


52


of free arms


32


and cooperate with free arms


32


to fully expand rain cover


23


to an expanded state as lower ring


34


is telescopingly moved upward along shaft


16


. Once rain cover


23


and support structure


24


are fully expanded to an expanded cover area of canopy


18


, inner ring


34


is secured in place by a conventional latch mechanism (not shown) on shaft


16


. The latch mechanism is not critical to the present invention and may be any typical latch mechanism as used in standard umbrellas. When expanded, the exterior of the cover is taut and sufficient to block rain and the like from entering bag


14


. Support structure


24


further movably cooperates to allow rain cover


23


to be fully collapsed to a compact cover area of canopy


18


, as support structure


24


is collapsed by moving lower ring


34


downward along shaft


16


. Although a particular umbrella support structure design is discussed herein, clearly other means for expanding and collapsing a canopy and rain cover of an umbrella may be implemented without affecting the scope of the present invention.




Protective cover


20


is preferably made of a durable, flexible and breathable material, such as a mesh netting, webbing, or the like, formed from synthetic or cloth fibers or other similar material, an example of which is the material of a bathing suit liner or the like. Protective cover


20


has an inner circumferential edge


56


and extends radially outward therefrom to an outer circumferential edge


58


. Inner edge


56


is secured to an inner ring


60


which further includes a circular opening


62


through its center. Inner edge


56


of protective cover


20


may be secured to inner ring


60


by sewing or otherwise securing the edge


56


to a plurality of holes or openings along inner ring


60


. As explained below, outer edge


58


is secured either to the underside of cover


23


, or to support structure


24


, or both.




As is also shown in

FIG. 4

, shaft


16


of golf bag umbrella


10


is extendable and retractable between a fully extended position, a lowered position and a closed position, and preferably includes an inner upper tube


70


and an outer lower tube


72


having a slightly larger diameter than upper tube


70


such that shaft


16


extends and retracts telescopically, with upper tube


70


slideably inserting within lower tube


72


. Lower tube


72


may further include a base handle


74


which rests upon a bottom surface


75


of golf bag


14


when golf bag umbrella


10


is placed within golf bag


14


. Base handle


74


may further be adapted to be fixably mounted to bottom surface


75


of golf bag


14


to further stabilize golf bag umbrella


10


within golf bag


14


.




Shaft


16


may further include a locking mechanism


78


, best seen in

FIGS. 6

A-C and


7


A-C, which secures upper tube


70


relative to lower tube


72


in each of the shaft positions. In order to allow golf bag umbrella


10


to easily extend and retract between the fully extended position and the lowered position, locking mechanism


78


preferably includes a spring


80


and an end piece


82


within shaft


16


, which engage one another and cooperate with upper and lower tubes


70


and


72


to secure shaft


16


in either an extended position (

FIG. 6A

) or a lowered position (FIG.


7


A). Spring


80


extends longitudinally within lower tube


72


from an anchored or fixed lower point


80




a


upwardly to an upper end


80




b


which contacts a lower end


83


of end piece


82


on upper tube


70


. End piece


82


is rotatably mounted within a lower end


70




a


of upper tube


70


and has a plurality of arms


88


extending outward from a center portion


89


and including angled upper ends


90


for engaging a plurality of teeth


92


on lower end


70




a


of upper tube


70


(FIG.


6


B). Upper tube


70


further includes a plurality of outwardly protruding tabs or guides


84


on its exterior surface


86


near lower end


70




a


. Lower tube


72


is formed with a plurality of radially inwardly projecting columns


94


extending longitudinally along an inner surface


96


of lower tube


72


such that a plurality of channels


98


are formed longitudinally within lower tube


72


between columns


94


. The sidewalls of lower tube


72


may be formed in this manner, or a molded inner section may be inserted within lower tube


72


to provide the channels and columns within lower tube


72


. At a lower end


100


of each column


94


is a notch


102


corresponding to upper ends


90


of arms


88


on end piece


82


, while an upper end of each channel


98


provides an upper positive stop. The lower end


100


of columns


94


may further provide a ramped surface


98


a immediately adjacent each channel to cause rotation of end piece


82


such that arms


88


move to engage channels


98


, as discussed below. The number of tabs


84


, arms


88


, columns


94


and channels


98


are substantially the same, and preferably three or more of each. However, clearly more or less of each may be provided without affecting the scope of the present invention.




When assembled, a cylindrical portion


82




a


of end piece


82


inserts into lower end


70




a


of upper tube


70


such that arms


88


of end piece


82


extend outward, engaging teeth


92


on lower end


70




a


and extending further outward to engage either notches


102


on lower end


100


of columns


94


in the lowered position (

FIGS. 7B and 7C

) or channels


98


in the extended position (FIG.


6


C). Tabs


84


on upper tube


70


slideably engage channels


98


to prevent rotation of upper tube


70


relative lower tube


72


and to contact the upper end (not shown) of channels


98


in the extended position, thereby providing a positive stop at a predetermined height above golf bag


14


. Spring


80


contacts lower end


83


of end piece


82


and pushes upwards on end piece


82


and upper tube


70


. The force exerted by spring


80


prevents accidental downward movement of upper tube


72


relative lower tube


72


and thus retains shaft


16


in each of its positions.




Base handle


74


preferably is also slidably secured to a lower end


72




a


of lower tube


72


of shaft


16


. Base handle


74


may include at least one upper hole


108




a


and at least one lower hole


108




b


, through which a locking pin or the like may protrude to fixedly secure base handle


74


relative to lower tube


72


. The locking pin may be in the form of a horseshoe clip


110


, which has one or more substantially rounded extensions


110




a


connected by a spring biased band


110




b


secured on lower tube


72


toward a lower end


72




a


thereof (FIG.


8


). The rounded extensions


110




a


protrude through handle


74


at one or more upper holes


108




a


or lower holes


108




b


, which correspond to the raised positions and storage position of golf bag umbrella


10


, respectively. Handle


74


and lower tube


72


are set at the raised position when canopy


18


is expanded for use and at the lowered, stored position when canopy is collapsed into its compact orientation.




As assembled, canopy


18


of golf bag umbrella


10


is secured at an upper end


70




b


of upper tube


70


of shaft


16


, such that upper ring


48


of support structure


24


is fixedly mounted at upper end


70




b


, while lower ring


34


of support structure


24


is slideably mounted along upper tube


70


at a point below upper ring


48


. Protective cover


20


secures along its outer circumferential edge


58


along underside


40


of rain cover


23


. Outer edge


58


of protective cover


20


may be secured under rain cover


23


at spaced points such as joints


36


, where free arms


32


of support structure


24


also secure to rain cover


23


, or alternatively, outer edge


58


may be sewn or otherwise attached to underside


40


of rain cover


23


, without affecting the scope of the present invention. Upper tube


70


extends through circular opening


62


in inner ring


60


of protective cover


20


, such that inner ring


60


is slideably positioned along upper tube


70


at a point below lower ring


34


of support structure


24


, thereby encasing free arms


32


and downward extending arms


46


of support structure


24


between rain cover


23


of canopy


18


and protective cover


20


. Inner ring


60


of protective cover


20


moves along upper tube


70


to enable protective cover


20


to fully expand under support structure


24


as canopy


18


is expanded, while further allowing protective cover


20


to collapse downward beneath support structure


24


as canopy


18


is collapsed. When canopy


18


is expanded, protective cover


20


is also expanded beneath support structure


24


such that protective cover


20


is tightly drawn between inner ring


60


and outer edge


58


, thereby providing a semi-rigid protective encasement of support structure


24


. Furthermore, when canopy


18


is collapsed, protective cover


20


drapes downward within the collapsed canopy, such that protective cover


20


is substantially contained within canopy


18


when the canopy is collapsed for storage.




Immediately above upper ring


48


of canopy


18


may be mounted a handle


22


, so that golf bag umbrella


10


is easily extended and retracted while it rests within golf bag


14


. Although handle


22


is shown as a golf ball shape, handle


22


may alternatively be a substantially ring-shaped handle


22


′, as shown in

FIG. 14

, or a grip-type handle


22


″ as shown in

FIG. 15

, without affecting the scope of the present invention.




When golf bag umbrella


10


is expanded for use in a golf bag


14


, lower tube


72


is moved upward within base handle


74


such that rounded extensions


110




a


protrude through upper holes


108




a


in base handle


74


. This positions canopy


18


and protective cover


20


at the lowered, in use position where a minimal clearance is provided between rain cover


23


and a typical long golf club such as a driver or the like. Arms


88


of end piece


82


engage lower ends


100


of columns


94


to prevent upper tube


70


and canopy


18


from rising upward beyond the lowered position, as spring


80


exerts a force upward on end piece


82


to retain this position (FIG.


7


B). This secures golf bag umbrella


10


in its lowered position such that canopy


18


rests immediately above the tallest of golf clubs


30


and extends radially outwardly to a position outside the top opening of golf bag


14


, thereby providing optimal protection of the golf clubs


30


and other items within golf bag


14


when it is raining on the golf course (FIG.


1


). Protective cover


20


extends radially outward from shaft


16


underneath free arms


32


of support structure


24


and is tightly drawn therebetween to prevent golf clubs


30


or other items within golf bag


14


from becoming entangled within support structure


24


. Protective cover


20


not only prevents damage to support structure


24


, as golf clubs


30


and support structure


24


no longer become entangled, but also functions to protect golf clubs


30


from being scratched or otherwise damaged by support structure


24


or other elements of canopy


18


.




When a golfer wishes to continue a round of golf while it is raining outside, golf clubs


30


must not only be kept dry, but also must be easily accessible to the golfer. Therefore, golf bag umbrella


10


may be easily extended such that canopy


18


is substantially above golf clubs


30


within golf bag


14


. This is accomplished simply by pressing downward on handle


22


, which depresses spring


80


, until upper ends


90


of arms


88


on end piece


82


are moved downward below a lower edge of notches


102


on columns


94


within lower tube


72


. At this point, end piece


82


rotates as upper ends


90


slide into a valley formed by teeth


92


to align arms


88


between notches


102


and channels


98


. As handle


22


is subsequently released, upper tube


70


and canopy


18


rise upward, as spring


80


pushes upward on end piece


82


, and arms


88


of end piece


82


rotate further as they slide along the ramped surface


98


a of the columns


94


and are thus guided into channels


98


. Spring


80


raises or extends shaft


16


until tabs


84


of upper tube


70


contact the upper end of channels


98


, thereby providing a positive stop at the extended position. At this extended position, golf clubs


30


may be easily removed from golf bag


14


for use by the golfer in the next shot, while likewise being easily replaced back into golf bag


14


upon completion of the shot, as the extended position provides adequate clearance between golf bag


14


and canopy


18


. Protective cover


20


further prevents golf clubs


30


or other items within golf bag


14


from becoming entangled within support structure


24


as they are removed from golf bag


14


. Once the selected golf club has been removed from the bag


14


, handle


22


may be pushed downward to return golf bag umbrella


10


to its lowered, in use position. Once handle


22


is pushed downward, and spring


80


is compressed, such that arms

88


rotate further to engage notches


102


in columns


94


, thereby preventing further upward movement of upper tube


70


and again securing shaft


16


in its lowered, in use position.




In situations where rain is not present on the golf course, canopy


18


may be compactly folded and wrapped about shaft


16


, as shaft


16


is retracted to its shortened, closed position shown in FIG.


5


. Shaft


16


may be shortened to the size of a small club such as a


9


iron, pitching wedge or the like, by setting golf bag umbrella to its lowered position and further sliding lower tube


72


into base handle


74


until rounded extensions


110




a


protrude through lower holes


108




b


in base handle


74


. This is accomplished easily by pressing inward on rounded extensions


110




a


as they protrude through upper holes


108




a


, and sliding lower tube


72


downward relative base handle


74


, while rounded extensions slide along an interior surface


74




a


of base handle


74


, until rounded extensions


110




a


engage lower holes


108




b


in base handle


74


. Rain cover


23


may include a band or strap


114


or other means to secure canopy


18


in a tightly wrapped closed position. Golf bag umbrella


10


may further include a sleeve


116


, into which canopy


18


and handle


22


may be inserted to further maintain canopy


18


in its compact, tightly wrapped orientation. By providing a sleek, compact umbrella such as described herein, golf bag umbrella


10


takes up a minimal amount of space within golf bag


14


when not in use. However, golf bag umbrella


10


could instead be stored along an outside surface of golf bag


14


as a typical golf umbrella is stored, without affecting the scope of the present invention.




In an alternate embodiment, as shown in

FIGS. 9 and 10

, a golf bag umbrella


10


′ may include a shaft


16


′ with a locking mechanism


78


′ which may include one or two curved spring bars or retainers


120


attaching at their ends


120




a


to lower tube


72


near an upper end


72




b


of that tube and extending substantially across a hollow opening


122


within lower tube


72


(FIGS.


12


and


13


). Spring retainers


120


slide along an outside surface


70




c


of upper tube


70


as upper tube


70


is extended and retracted within lower tube


72


, and flex inward at each of a plurality of detents or indentations


124


,


126


and


128


positioned along upper tube


70


and corresponding to the extended position shown in

FIG. 9

, lowered position shown in FIG.


10


and closed position similar to umbrella


10


in

FIG. 5

, respectively, of shaft


16


′. Indentations


124


,


126


and


128


may be small crimps on upper tube


70


or may be a circumferential indentation or narrowing of upper tube


70


at each predetermined position, as best shown in FIG.


11


. Furthermore, indentations


124


,


126


and


128


are preferably rounded at their upper and lower edges


130


, to allow for easy movement of upper tube


70


from one position to the next. Although the spring retainer mechanism is preferred, clearly other locking mechanisms may be implemented without effecting the scope of the present invention. For example, as shown in

FIG. 11

, a ball


132


and spring


133


retainer may be used which similarly engages indentations


124


,


126


or


128


to hold the shaft in each of its three positions.




In order to prevent upper tube


70


from being fully removed from lower tube


72


, as shaft


16


is fully extended to its extended position, a means for providing a positive stop may be included within shaft


16


. In this embodiment, as best shown in

FIG. 11

, this stop is in a form of a rigid flange


134


extending radially outward at a lower end


70




a


of upper tube


70


. Lower tube


72


include s a radially inward extending circumferential indentation or detent


136


located toward upper end


72




b


of lower tube


72


at a position immediately beneath locking mechanism


78


′. Detent


136


on lower tube


72


protrudes inwardly into hollow opening


122


of lower tube


72


, forming an inner opening that is smaller than the diameter of flange


134


on upper tube


70


. Therefore, as shaft


16


′ is fully extended beyond its extended position shown in

FIG. 9

, such that indentation


124


is pulled above locking mechanism


78


′, flange


134


on upper tube


70


engages detent


136


on lower tube


72


to prevent upper tube


70


from being further removed from lower tube


72


. Clearly other stop means may instead be implemented to prevent dis assembly of shaft


16


without affecting the scope of the present invention.




In order to secure golf bag umbrella


10


′ in this lowered position, locking mechanism


78


′ on lower tube


72


engages indentation


126


on upper tube


70


at a predetermined height such that the lowered position provides minimal clearance between rain cover


23


and a typical long golf club such as a driver or the like. Golf bag umbrella


10


′ is then easily extended by pulling upward on handle


22


so that upper tube


70


slides upward and outward from lower tube


72


until locking mechanism


78


′ engages indentation


124


on upper tube


70


. Furthermore, when fully retracted to its stored position, locking mechanism


78


′ may engage an additional indentation


128


on upper tube


70


, such that golf bag umbrella


10


′ is approximately the size of a typical short iron, such as a pitching wedge or a


9


iron, within golf bag


14


.




Therefore, each embodiment of the present invention provides optimal protection of golf clubs and other items within a golf bag when the golf bag umbrella is in its lowered and expanded position, as shown in

FIG. 1

, with canopy


18


covering the golf bag and extending outward beyond the open cavity of the golf bag. Protective cover


20


provides a means to both protect support structure


24


and the golf clubs from being damaged through contact with one another, while also preventing the golf clubs from being entangled within support structure


24


while the golf bag and its contents are transported along the golf course. Accordingly, sudden movements encountered while the golf bag is transported do not result in the golf clubs becoming entangled within support structure


24


, as in cases where a typical umbrella is positioned over a golf bag. Not only does protective cover


20


prevent damage to both the golf clubs and support structure


24


, but it further avoids additional frustration on the part of the golfer as the golfer attempts to remove a selected club from within the golf bag for the next shot. As the golf clubs are prevented from becoming entangled within support structure


24


, the clubs will be easily removable from the golf bag once the golf bag umbrella is extended to its raised position shown in FIG.


2


. Once the club has been removed, the golf bag umbrella may be easily returned to its lowered position to continue to provide protection for the clubs remaining in the golf bag while the golfer takes the next shot. Furthermore, the golf bag umbrella further improves upon a typical golf bag umbrella design in that canopy


18


of the golf bag umbrella may be tightly and compactly folded and wrapped about shaft


16


, which may also be retracted into a shorter, closed position, such that the golf bag umbrella only takes up approximately the same amount of space as a typical short golf club. The end result is a golf bag umbrella which is easy to move between its extended and lowered positions, and that provides optimal protection to the golf clubs within a golf bag from both adverse weather conditions and from the internal components of the umbrella canopy itself.
